CVSS: 8.1EPSS: 3%CPEs: 60EXPL: 3CVE-2019-6974 – Linux - 'kvm_ioctl_create_device()' NULL Pointer Dereference
https://notcve.org/view.php?id=CVE-2019-6974
In the Linux kernel before 4.20.8, kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandles reference counting because of a race condition, leading to a use-after-free. En el kernel de Linux en versiones anteriores a la 4.20.8, kvm_ioctl_create_device en virt/kvm/kvm_main.c gestiona de manera incorrecta el conteo de referencias debido a una condición de carrera, lo que conduce a un uso de memoria previamente liberada. A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor implements its device control API. While creating a device via kvm_ioctl_create_device(), the device holds a reference to a VM object, later this reference is transferred to the caller's file descriptor table. If such file descriptor was to be closed, reference count to the VM object could become zero, potentially leading to a use-after-free issue. • https://www.exploit-db.com/exploits/46388 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cfa39381173d5f969daf43582c95ad679189cbc9 http://www.securityfocus.com/bid/107127 https://access.redhat.com/errata/RHBA-2019:0959 https://access.redhat.com/errata/RHSA-2019:0818 https://access.redhat.com/errata/RHSA-2019:0833 https://access.redhat.com/errata/RHSA-2019:2809 https://access.redhat.com/errata/RHSA-2019:3967 https://access.redhat.com/errata/RHSA-2020:0103&# • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVSS: 7.5EPSS: 4%CPEs: 16EXPL: 1CVE-2018-16890 – curl: NTLM type-2 heap out-of-bounds buffer read
https://notcve.org/view.php?id=CVE-2018-16890
libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds. Libcurl, desde la versión 7.36.0 hasta antes de la 7.64.0, es vulnerable a una lectura de memoria dinámica (heap) fuera de límites. La función que gestiona los mensajes entrantes NTLM de tipo 2 ("lib/vauth/ntlm.c:ntlm_decode_type2_target") no valida los datos entrantes correctamente y está sujeta a una vulnerabilidad de desbordamiento de enteros. • https://github.com/michelleamesquita/CVE-2018-16890 http://www.securityfocus.com/bid/106947 https://access.redhat.com/errata/RHSA-2019:3701 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16890 https://cert-portal.siemens.com/productcert/pdf/ssa-436177.pdf https://curl.haxx.se/docs/CVE-2018-16890.html https://lists.apache.org/thread.html/8338a0f605bdbb3a6098bb76f666a95fc2b2f53f37fa1ecc89f1146f%40%3Cdevnull.infra.apache.org%3E https://security.netapp.com/advisory/ntap-20190315-0001 https://sup • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound •

CVSS: 7.8EPSS: 1%CPEs: 152EXPL: 0CVE-2018-5391 – The Linux kernel, versions 3.9+, IP implementation is vulnerable to denial of service conditions with low rates of specially modified packets
https://notcve.org/view.php?id=CVE-2018-5391
The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size. El kernel de Linux en versiones a partir de la 3.9 es vulnerable a un ataque de denegación de servicio (DoS) con tasas bajas de paquetes especialmente modificados que apuntan hacia el reensamblado de fragmentos de IP. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2018-004.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200115-01-linux-en http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/105108 http://www.securitytracker.com/id/1041476 http://www.securitytracker.com/id/1041637 https://access.redhat.co • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
